NASA AND RISK ESTIMATION

I read once our brain is not good at evaluating risks and our capacities, underestimating the first and overestimating the second. That allow progress somehow, because failures of others help us to find a right way, we gave quite safe planes nowadays...........though many would have not try to fly at the beginning if they realized the real chances of success.

Organizations are a congregation of brains, egos, procedures and sometimes diverging interest, even the most advanced ones seem to face similar problems as individual brains, as we can read in this interesting article about NASA re-studying shuttle missions risks.
